I’m using the Homey Pro 2019 model and it updated automatically to firmware 12.11.0 yesterday morning. Since then I can’t access a single device I’ve installed. If I try to restart any app it shows error code “invalid\_state\_has\_process”, I’ve tried unistalling and installing the apps again and adding the device once more but it can’t find anything and times out. I’ve tried PTP and I have changed the power supply so that should not be an issue. Am I the only one where this new firmware totally broke my Homey? 😅 ---

It seems that the configuration got corrupted. Do you have the backup subscription? In that case, you can factory reset your Homey and restore from a backup afterwards ---

Sadly I don’t have the backup subsciption. It’s looking like I have to do a factory reset and start adding all devices once again. ---

You should first contact Athom before performing a reset > **[Support | Homey](https://homey.app/en-us/support/)** ---

No reset needed now imho, and without a backup (order it now) a reset destroys all of your work. You can first perform this possible fix: - start Homey in recovery mode (turn it up-side-down a minute after power up), - per mobile app, go to “Add new Homey” (_sounds odd, but that’s just the only way to connect to your Homey in recovery mode_) and follow instructions to connect it to wifi - then navigate to “Full software download” and select it → This installs the firmware from scratch, and shouldn’t touch your data. I’ve read about one case of issues after Pro 2016-2019 v12.11.0 update, it killed zigbee. My preference, as you now might understand, is to install firmware updates myself. I can recommend the backup subscription by 100%! It’s only €10/y. It has saved my ass for several times now, either due to VSFU (Very stupid fuck up) or hardware failure. ---

Thanks, I will definitely try this out. Doing a reset is the last resort. ---

If you perform it exactly as Peter wrote, you will not loose anything, naturally backup is a very good thing to have as safety measure. ---

Update: After trying out the recovery mode and reinstalling the update the issue has now been resolved and will not have to perform a reset. Everything is working perfectly now! Special thanks to @Peter_Kawa for your help 👏 Thank you also to Sharky and Sven! ---

Same for me, trying the solution provided in this thread as we speak. Seems to work
